I've seen that pic many times but never in that detail. There's something funny about it but I can't put my finger on it. I was under the impression that the Bristol Aircraft Company's involvement was in their expertise in making large fibreglass mouldings (which was very high tech at the time,) not in the wind tunnel tests. In fact very early Airflow fairings had a "Made by The Bristol Aircraft Company" badge inside them. If that really is their wind tunnel then the bike is facing the wrong way for a test, the fan is behind it. Also, the Airflow Twins had a siamese exhaust system with the pipe exiting on the right, that one clearly has separate pipes! The tie up with Bristol isn't surprising, during WW2 they had the underground factory next to Enfield's at Bradford on Avon where they made aero engines. Later Enfield Precision Engineers, making the Mk1A and Mk2 Interceptors, did contract work for Bristol on the Bloodhound missile system and carried on for a while with this when motorcycle production stopped. Thanks for showing the picture!

Probably sucking not blowing . BAC ( Filton Bristol) also held every workshop manual for every model and make of british bike, and if I think all the blue prints, why I don't know but my mates who worked there back in the 60s were never short of information when building specials on the night shift.

Well, hereby lies the worms from the can...



I have seen more than picture of a MM airflow, and they seem to have separate pipes... I just go look...










Yes, here we go, not sure if the middle pic is a MM or not.















Stay tuned for more on another exciting RE mystery!

Hi looks more like an artists drawing I thought the bike would be faceing the fan no flash shadows but fan is blurred flash would have stopped the fan image looks too sharp for available light photography a bit of pr bull.

Yay YAY! Got the proof, solved the mystery. The MM airflow had two pipes! YAY!



Scaly's RE stuff



Go to the link above, scroll down to 'Kevin's Corner' there is a black/white supplement to the 1958 parts list book for standard and airflow models. Open it, and just over half way down on page 6 it lists, 'Exhaust pipe R.H.' and under that, Exhaust pipe L.H.' and under that, 'Silencer clip and associated parts, 2 off each'.



YAY! Self chuffed or what!

If you blow the air then it spreads out. Mostly, you suck it, with a similar sized aperture in front, so the air is coming through the test area is parallel. Even better when they used to inject smoke to create lines, so you could see the air bend over wings and things!

Have another look at the "wind tunnel" picture and read the caption. I think that is a photo of Bristol's stand at the annual Motorcycle Show at Earl's Court London. Which would explain a lot, not least the rather plastic expression of the dummy rider!

REgards, Mark

OK, it was probably set up for the show, it says, "in London' and, 'motor show'



sod that, what about my researched discovery that a MM airflow had two pipes? Where's my glory and adoration?



I'll go back to me book then!
